Yes—Lightroom can handle most of this during import. When importing from another drive, use Move (or Copy if you want to verify first) and set the Destination to organize By Date. Lightroom’s default folder organization can match a year/month/day structure, and it shows a preview of the resulting folders before you run the import.

It can also skip suspected duplicates, which helps when consolidating files from multiple drives. If you use Move, Lightroom transfers the files into the new dated folder structure and leaves duplicate files behind on the source drive rather than re-importing them.

If your goal is to keep the original files untouched, Lightroom can do that as long as you avoid applying develop presets on import. Setting the default import preset to something like Zeroed ensures Lightroom won’t alter their appearance on import. The files themselves remain unchanged.

So Lightroom is suitable for:

• moving/copying from external drives
• organizing by date
• avoiding duplicate imports
• keeping originals intact

What the answer does not confirm is checksum-style copy verification or automatic deletion of exact duplicates already present at the destination.
